IPv6 addressing is supported for IES IP interfaces in access-uplink mode.
In access-uplink mode, IES IP interfaces associated with access-uplink SAPs support IPv6 addressing. IPv6 can be used for in-band management of the node using the IES IP interface.
IPv6 IES IP interfaces on access-uplink SAPs are only supported on 7210 SAS-T operating in access-uplink mode.
IPv4 and IPv6 route table lookup entries are shared. Before adding routes for IPv6 destinations, route entries in the routed lookup table needs to be allocated for IPv6 addresses. This can be done using the CLI command config> system> resource-profile> router> max-ipv6-routes. This command allocates route entries for /64 IPv6 prefix route lookups. The system does not allocate any IPv6 route entries by default and user needs to allocate some resources before using IPv6. For the command to take effect the node must be rebooted after making the change. For more information, see the following example and the 7210 SAS-Mxp, R6, R12, S, Sx, T Interface Configuration Guide.
A separate route table (or a block in the route table) is used for IPv6 /128-bit prefix route lookup. A limited amount of IPv6 /128 prefixes route lookup entries is supported. The software enables lookups in this table by default (that is no user configuration is required to enable Ipv6 /128-bit route lookup).
IPv6 interfaces can be created without allocating IPv6 route entries.
Following features and restrictions is applicable for IPv6 IES IP interfaces:
IPv6 interfaces supports only static routing.
Only port-based ingress QoS policies are supported.
IPv6 filter policies can be used on SAP ingress and egress.
Routing protocols, such as OSPFv3, and others are not supported.
A limited amount of IPv6 /128 prefixes route lookup entries is supported.
